As shown in FIG. 1, the stand S is configured to be detachably attached to a bicycle, and a first support column 1 and a second support unit that is rotatably connected to the first support column 1. The support 2 is provided.

  The 1st support | pillar 1 and the 2nd support | pillar 2 are the leg parts 11 and 21 arrange | positioned rather than the rotating shaft X (refer FIG. 2A) with respect to the 1st support | pillar 1 of the 2nd support | pillar 2. And sandwiching portions 12 and 22 disposed above the rotation axis X, respectively.

  Specifically, each of the first support column 1 and the second support column 2 is made of a single metal rod, for example, an aluminum alloy rod.

  The first support column 1 includes a rod-shaped first main body portion 13 extending in the up-down direction and a first engagement portion 14 protruding laterally from the first main body portion 13.

  As for the 1st main-body part 13, the lower part of the 1st engaging part 14 comprises the leg part 11, and the upper part of the 1st engaging part 14 comprises the clamping part 12. FIG. The leg portion 11 and the sandwiching portion 12 are provided side by side in the vertical direction so as to overlap each other when viewed from the longitudinal direction of the first main body portion 13 (see FIG. 2B).

  As shown in FIGS. 2A and 2B, the first engaging portion 14 is formed by bending a portion between the sandwiching portion 12 and the leg portion 11 of the first support column 1 into a substantially U shape. The first main body 13 is formed in a substantially U shape when viewed from the longitudinal direction.

  One end of the U-shape of the first engagement portion 14 is connected to the upper end of the leg portion 11, and the other end is connected to the lower end of the holding portion 12. As shown in FIG. 2C, the distance D <b> 1 (shortest distance) between the leg portion 11 and the sandwiching portion 12 is narrower than the thickness of the metal rod constituting the second support column 2.

  As shown in FIG. 1, the second support column 2 includes a rod-shaped second main body portion 23 extending in the vertical direction, and a second engagement portion 24 protruding laterally from the second main body portion 23.

  In the second main body 23, the lower part of the second engagement part 24 constitutes the leg part 21, and the upper part of the second engagement part 24 constitutes the clamping part 22. The leg portion 21 and the clamping portion 22 are provided side by side in the vertical direction so as to overlap each other when viewed from the longitudinal direction of the second main body portion 23.

  As shown in FIG. 2A, the second engaging portion 24 is formed by bending a portion between the sandwiching portion 22 and the leg portion 21 of the second support column 2 into a substantially U shape. The second engaging portion 24 is formed in a substantially U shape when viewed from a direction orthogonal to the longitudinal direction of the second support column 2 and penetrates in a direction orthogonal to the longitudinal direction of the second support column 2. An opening 241 is formed.

  One end of the U-shape of the second engagement portion 24 is connected to the upper end of the leg portion 21, and the other end is connected to the lower end of the holding portion 22. The distance D <b> 2 (shortest distance) between the leg portion 21 and the sandwiching portion 22 is narrower than the thickness of the metal rod constituting the first support column 1.

  The 1st support | pillar 1 and the 2nd support | pillar 2 are connected because the 1st engaging part 14 and the 2nd engaging part 24 engage. Specifically, as shown in FIG. 2B, the first engaging portion 14 passes through the opening 241 inside the second engaging portion 24 in a direction orthogonal to the longitudinal direction of the second main body portion 23. Thus, the second engaging portion 24 is engaged.

  When assembling the first support column 1 to the second support column 2, for example, the second engagement portion 24 of the second support column 2 is elastically deformed to widen the gap between the sandwiching portion 22 and the leg portion 21. Then, the 1st engaging part 14 and the 2nd engaging part 24 can be engaged by inserting the 1st engaging part 14 from the inside.

  In the stand S configured as described above, as shown in FIG. 1, the second support column 2 is a portion that engages with the first engagement unit 14 with the second engagement unit 24 of the first engagement unit 14. It can be rotated around a rotation axis X passing through the center of the portion (the portion disposed inside the opening 241) (see FIG. 2A). Further, since the rotation axis X is disposed between the first main body portion 13 and the second main body portion 23, the stand S has a pair of leg portions 11 and 21 when the second support column 2 rotates. As the angle increases, the pair of sandwiching portions 12 and 22 become narrower.

  The first support column 1 and the second support column 2 are used apart from each other as shown in FIG. 1 because the second engagement portion 24 moves along the U shape of the first engagement portion 14. It is possible to switch between the state and the storage state closest to each other as shown in FIG.

  A cap R1 made of rubber is attached to each of the leg portions 11 and 21 so as to cover the lower end thereof.

  And each clamping part 12 and 22 is attached to the part which contacts the axis | shaft SH of pedal PE, and the covering member R2 which consists of the rubber | gum formed in the cylindrical shape which covers the surrounding surface of the clamping parts 12 and 22 is attached.

Next, how to use the stand S will be described.
When the bicycle B is parked, first, as shown in FIG. 1, the first support column 1 and the second support column 2 are expanded so that the stand S is in use. Then, as shown in FIGS. 4 and 5, the first engagement portion 14 and the second engagement portion 24 of the stand S are arranged below the shaft SH of one pedal PE so that a pair of clamping The shafts SH of the pedal PE are sandwiched between the portions 12 and 22. At this time, since the second engagement portion 24 hits the shaft SH from below, the shaft SH is sandwiched from three sides by the pair of sandwiching portions 12 and 22 and the second engagement portion 24. As a result, the shaft SH is unlikely to be detached from the stand S, so that the bicycle B can be stably held. In order to firmly clamp the shaft SH, the contact portion of the pair of sandwiching portions 12 and 22 with the shaft SH and the contact portion of the second engagement portion 24 with the shaft SH surround the center of the shaft SH. It is desirable.

  Next, as shown in FIG. 6, the pair of leg portions 11 and 21 are erected on the floor surface F. Accordingly, since the bicycle B is supported by the stand S, the bicycle B is held in a standing state.

  At this time, the crank CR of the bicycle B may be shifted to the rear wheel RW side from the vertical lower side of the rotation axis CR1 of the crank CR. By doing in this way, even if an upward force is applied to the shaft SH of the pedal PE from the first engaging portion 14 and the second engaging portion 24, the pedal PE does not rise unless the wheel rotates forward. Bicycle B is easy to stabilize. Furthermore, since the wheel can be prevented from turning forward by keeping the handle toward the side where the stand S is provided, the bicycle B is more stable.

  Further, when the stand S is set up, first, the leg portion of the column near the front wheel FW (the leg portion 11 of the first column 1 in FIG. 5) is set up on the floor surface F, and then the side near the rear wheel RW. It is preferable to stand on the floor F while pulling the leg portion (the leg portion 21 of the second column 2 in FIG. 5) toward the rear wheel RW side (rear side). In this way, the distance between the leg portions 11 and 21 and the height of the first engagement portion 14 and the second engagement portion 24 (the positional relationship of the pedal SH axis SH with respect to the rotation axis CR1 of the crank CR) are adjusted. Since it is easy to do, the stand S can be made to stand stably.

  When the stand S is not used, the stand S is removed from the shaft SH of the pedal PE, and the first support column 1 and the second support column 2 are brought close to each other as shown in FIG.

  Note that a clip may be attached to the frame of the bicycle B so that the stand S can be easily carried, and the stand S in a stored state may be held in the clip. You may fix a clip to a flame | frame using the volt | bolt for fixing the drink holder provided in the flame | frame, for example.

The operation and effect of the stand S configured as described above will be described.
When the stand S supports the bicycle B in a standing state, the pair of legs 11 and 21 are about to open with the weight of the bicycle B. If it does so, the space | interval of a pair of clamping parts 12 and 22 will narrow. As a result, the shaft SH of the pedal PE can be firmly held by the holding portions 12 and 22, so that the stand S is firmly fixed to the bicycle B.

  In addition, since the sandwiching portions 12 and 22 are each provided with rubber at a portion that contacts the shaft SH of the pedal PE, the sandwiching portions 12 and 22 are less likely to slip with respect to the shaft SH of the pedal PE, and the sandwiching portion 12 , 22 can firmly hold the shaft SH of the pedal PE.

  And since the rubber | gum is each provided in the lower end of the leg parts 11 and 21, the leg parts 11 and 21 are hard to slip with respect to the floor surface F, and the bicycle B can be supported stably by the stand S. it can.

  Further, the interval between the sandwiching portion 12 and the leg portion 11 of the first support column 1 is narrower than the thickness of the second support column 2, and the interval between the sandwiching portion 22 and the leg portion 21 of the second support column 2 is set to the first interval. Since it is narrower than the thickness of the column 1, the engagement between the first engagement portion 14 and the second engagement portion 24 is difficult to disengage. Accordingly, the bicycle B can be stably supported by the stand S.

  And when the stand S is not used, it can be made more compact than the use state by putting it in the housed state, and portability is improved.

  In addition, since the stand S includes only the first support column 1 and the second support column 2 made of a single metal rod, the configuration is simple and the weight can be reduced.
